  • Profiling: Use Android Studio Profiler to monitor frame rate (FPS). Drops below 60 FPS indicate rendering issues.
  • StrictMode: Enable StrictMode to detect long operations on the main thread that block rendering.
    StrictMode.setThreadPolicy(StrictMode.ThreadPolicy.Builder()
    .detectAll() // Detect all potential thread issues
    .penaltyLog() // Log violations
    .build())
StrictMode.setVmPolicy(StrictMode.VmPolicy.Builder()
    .detectAll() // Detect all potential VM issues
    .penaltyLog() // Log violations
    .build())
  • "Show layout bounds" function: Enable this option in developer menu to visually identify redraws and their boundaries, which can help detect excessive redraws.
  • "GPU rendering profile" function: Enable this option in developer menu to visualize the rendering time of each frame and identify bottlenecks.
  • Error and performance tracking libraries: Use third-party libraries like Firebase Performance Monitoring or Sentry to automatically collect app performance data in real-time, including rendering lag information.
  • Custom monitoring: Implement code to measure rendering time, e.g., using Choreographer.postFrameCallback(), and log or send this data to a server.
    Choreographer.getInstance().postFrameCallback { frameTimeNanos ->
    // frameTimeNanos - current frame start time in nanoseconds
    // Measure time elapsed since previous frame,
    // and determine if it exceeds the acceptable threshold (~16.6 ms for 60 FPS)
}
